ABC renews 'Grey's', 'Modern Family', more

ABC has confirmed that it has ordered more seasons of six of its shows.

TV Line reports that the network made the announcement at the Television Critics Association tour.

Grey's Anatomy and its spinoff Private Practice will both return for their eighth and fifth seasons respectively.

Meanwhile, ABC handed its comedies Modern Family, The Middle and Cougar Town third seasons. Crime drama Castle, which stars Nathan Fillion and Stana Katic, was picked up for a fourth season.

However, the network has still not confirmed the future of Sunday night shows Desperate Housewives and Brothers & Sisters. Housewives creator Marc Cherry is thought to have a deal for two more seasons, but the cast are only in contract until the end of the current run. Negotiations are said to be ongoing.

Elsewhere, sources suggested that there is a 50% chance that Brothers & Sisters will come to an end after its current fifth season.
